Git Tips

Checkout GitHub pull requests locally

只針對單一 repo

假設先前跑過以下 command :

$ git add remote add github git://github.com/USERNAME/REPO.git

那 repo 裡的 .git/config 會包含這些資訊：

[remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = git@github.com:USERNAME/REPO.git

接下來只要加上一行變成：

[remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = git@github.com:USERNAME/REPO.git
    fetch = +refs/pull/*/head:refs/remotes/origin/pr/*

加完後只要下 fetch 就可以取回 GitHub 上的 PRs

$ git fetch github
From git://github.com/USERNAME/REPO
- [new ref]         refs/pull/1/head -> origin/pr/1
- [new ref]         refs/pull/2/head -> origin/pr/2
...

切到 PR：

$ git checkout pr/1
Branch pr/1 set up to track remote branch pr/1 from github.
Switched to a new branch 'pr/1'

global 設定

$ git config --global --add remote.origin.fetch "+refs/pull/*/head:refs/remotes/origin/pr/*"

只抓特定 PR

$ git fetch github pull/1/head:pr/1
From git://github.com/USERNAME/REPO
- [new ref]         refs/pull/1/head -> pr/1
$ git checkout pr/1
